On whether it is feasible to use glycolic acid toner after peroxybenzoyl cleansing
There is a recent question, can you continue to use glycolic acid toner after using peroxybenzoyl cleansing. This question is related to the order of skin care and the adaptation of ingredients, which must be carefully investigated.
Peroxybenzoyl, commonly used in cleansing products, has antibacterial and anti-inflammatory properties, and is mostly used to treat acne and other skin diseases. It acts on the skin, can break the cell wall of Propionibacterium acne, and helps exfoliate, but it is strong, or causes skin dryness, irritation, and even redness and desquamation.
Glycolic acid toner, containing glycolic acid, belongs to fruit acids. It has the effect of promoting keratin metabolism, brightening skin tone, and smoothing skin. However, because it can loosen the connections between keratinocytes and increase skin permeability, the skin is more sensitive to irritants after use.
After cleansing with peroxybenzoyl, the skin has been irritated to a certain extent, and the stratum corneum may be in a relatively fragile state. At this time, if you use glycolic acid toner, the two stimulations will be superimposed, and the skin may be unbearable, causing increased discomfort, such as tingling, redness and swelling.
However, if the skin has good tolerance and after gradually building up tolerance, first use a small amount of benzoyl peroxide to cleanse the face, then wipe it lightly with diluted glycolic acid toner, and closely observe the skin's reaction, or you can try it. However, it is advisable to use it slowly at the beginning, and then gradually increase the frequency and dosage when the skin adapts.
Using glycolic acid toner after cleansing with benzoyl peroxide is not a wise move for skin with weak tolerance; and those with strong tolerance also need to act cautiously to protect skin health.
